Modelling the Spread of SARS-CoV2 and its variants. Comparison with Real Data. Relations that have to be Satisfied to Achieve the Total Regression of the SARS-CoV2 Infection
Giorgio Sonnino, Philippe Peeters, Pasquale Nardone
This work provides an overview on deterministic and stochastic models that have previously been proposed by us to study the transmission dynamics of the Coronavirus Disease 2019 (C…
Turbulent Transport in Tokamak-plasmas: A Thermodynamic Approach
Giorgio Sonnino, Philippe Peeters, Pasquale Nardone +1
In previous work we provided the explicit form of the nonlinear PDEs, subjected to the appropriate boundary conditions, which have to be satisfied by transport coefficients for sys…
Simple algorithm for GCD of polynomials
Pasquale Nardone, Giorgio Sonnino
Based on the Bezout approach we propose a simple algorithm to determine the {\tt gcd} of two polynomials which doesn't need division, like the Euclidean algorithm, or determinant c…
Modelling the Spreading of the SARS-CoV-2 in Presence of the Lockdown and Quarantine Measures by a "Kinetic-Type Reactions" Approach
Giorgio Sonnino, Philippe Peeters, Pasquale Nardone
We propose a realistic model for the evolution of the COVID-19 pandemic subject to the lockdown and quarantine measures, which takes into account the time-delay for recovery or dea…
A Stochastic Compartmental Model for COVID-19
Giorgio Sonnino, Fernando Mora, Pasquale Nardone
We propose two stochastic models for the Coronavirus pandemic. The statistical properties of the models, in particular the correlation functions and the probability density functio…
Determination of the Dynamic ITER Energy Confinement Time Scalings
Giorgio Sonnino, Alberto Sonnino, Jarah Evslin +1
We derive the differential equation, which is satisfied by the ITER scalings for the dynamic energy confinement time. We show that this differential equation can also be obtained f…
Entropy of Difference
Pasquale Nardone
Here, we propose a new tool to estimate the complexity of a time series: the entropy of difference (ED). The method is based solely on the sign of the difference between neighborin…
Stationary distribution functions for Tokamak-plasmas in the weak-collisional transport regime by MaxEnt principle
Giorgio Sonnino, Philippe Peeters, Alberto Sonnino +2
In previous works, we derived stationary density distribution functions (DDF) where the local equilibrium is determined by imposing the maximum entropy (MaxEnt) principle, under th…
Reference Distribution Functions for Magnetically Confined Plasmas from the Minimum Entropy Production Theorem and the MaxEnt Principle, subject to the Scale-Invariant Restrictions
Giorgio Sonnino, Alessandro Cardinali, Gyorgy Steinbrecher +3
We derive the expression of the reference distribution function for magnetically confined plasmas far from the thermodynamic equilibrium. The local equilibrium state is fixed by im…
Derivation of Reference Distribution Functions for Tokamak-plasmas by Statistical Thermodynamics
Giorgio Sonnino, Alessandro Cardinali, Philippe Peeters +2
A general approach for deriving the expression of reference distribution functions by statistical thermodynamics is illustrated, and applied to the case of a magnetically confined…
Linear And Nonlinear Arabesques: A Study Of Closed Chains Of Negative 2-Element Circuits
Chris Antonopoulos, Vasileios Basios, Jacques Demongeot +2
In this paper we consider a family of dynamical systems that we call "arabesques", defined as closed chains of 2-element negative circuits. An -dimensional arabesque system has…
Conformal transformations in classical gravitational theories and in cosmology
Valerio Faraoni, Edgard Gunzig, Pasquale Nardone
In recent years, the use of conformal transformation techniques has become widespread in the literature on gravitational theories alternative to general relativity, on cosmology, a…
